This unassuming townhouse at 189 Luquer Street starts out with the advantage of being in a particularly cool little section of otherwise postcard-perfect Carroll Gardens, near Gowanus and the Columbia Street Waterfront without being a hike to the subway and steps from some of the best restaurants in the borough (Buttermilk Channel, Frankie’s). While the home may not be palatial at 1,848 square feet, there are four bedrooms and a lovely outdoor space. It’s move-in-ready if not decked out in marble and European kitchen gear, and the current owners clearly know the value of colorful surroundings. Rather than the usual shades of pale, crayola colors wake the bedrooms from boredom, and bright pops of red and riots of pattern appear in unexpected places

From the outside, this brick home is pure brownstone Brooklyn. Inside, it’s a mix of original details like marble mantles, rustic wood floors, hand-carved banisters, high ceilings and plaster moldings and colorful, whimsical additions.

On the garden floor, a living room wall mural blooms in hues of blue and rose. A bright renovated kitchen that opens into a formal dining room and living room, and a wall of windows overlooks a private garden for real blooms. Stone countertops get the work done, but color is welcome as well, here in a crimson pebble and resin backsplash.

On the next floor, bedrooms are candy-hued in tangerine and cyan, and a bonus room is perfect as a home office or dream closet. Also here is a full bath with a glass-enclosed shower.

On the top floor, a huge master suite with plenty of closet space offers a massive bedroom that could easily be converted into two (which it apparently once was), in keeping with the rest of the home’s flexibility and casual cool.
